Strange Tales, Vol. 1 #161 (1967)

Project: Blackout, Part II: The Second Doom! / And a Scourge Shall Come Upon You!
"The Second Doom!" - Nick continues relating the tale of how he and Cap stopped the alien invasion. Cap was saved by Reed Richards and Ben Grimm, who promptly assembled the devices needed to overpower the aliens, though the power draw caused a major blackout along the east coast. Once the tale is told, Jimmy Woo reveals the true nature of the threat: one of his old adversaries has returned. "And A Scourge Shall Come Upon You!" - Mordo casts Strange out into another dimension, ignoring Strange's pleas to prepare for the coming of the Living Tribunal. Once there, he is met by Victoria Bentley, who now remembers the events of Strange Tales #114. They learn that they have been summoned by Nebulos, Lord of the Planets Perilous, for purposes unknown.
